ENGINE

sold a AS IS TRADE IN vehicle that had no warning lights on dashboard or window info on safety defective emmisons and ecm and has not been very helpful with my vehicle I have not been able to drive because of safety concerns with recent discovery of codes that showed after getting a new battery for my new way of commuteing to work and live daily activity like most with a car I laid 2,050.15 and was told many times at test drive that it was amazing running sports car and mentioned he only had to replace valve cover gasket before it was able to be sold and at time of payment with test drive only showing signs of low rpm and throttle idle on test drive so trusting that the owner was telling me the truth I purchased and drove car home I needed gas because fuel was empty and when I went to pump into tank I got major clicking of the handle like my new car wouldn't take fuel for some weird reason owner at dealership was called 5 mins after buying on auto lot to express major concern with pumping gas he again said vehicle was inspected with nothing of concern now finding that it is going to cost many thousands to repair emmisons system And fault codes with total programing with abs and to cost more than anyone can honestly afford now I'm drained of my savings and have no hope of finding a solution so my car isn't parked because of failure of hidden defects I would of never invested my whole savings on a car if information was shown for defective vehicle system parts.i want the owner to honor his misleading auto fraud and in anyway help with safety emmisons compromised part replacement so my vehicle I purchased will drive like promised at business or replace it with a vehicle that is safe for the road without hidden errors I am very emotionally distressed over finding a solution for this unexpected misfortune I've been experiencing life gets very difficult without assess to a safe vehicle it has cost me to much I shouldn't have to suffer for his fraudulent actions

2007 Scion TC Plano, TX

ENGINE

When I bought this car, there was a couple recalls within 5 years of owning. One was fixed. The second was an oil consumption issue that my car passed by 100 miles and I was told it would not be covered. For the last few years the oil consumption has gotten worse. I have to put oil in the car when the light comes on, which is anywhere between 1k and 2k miles. As I'm driving, it can smell of burning, or start shaking, etc.

ENGINE AND ENGINE COOLING

The contact owns a 2006 Scion TC. The contact stated that after performing a vehicle inspection of the engine compartment, he became aware that the coolant reservoir was abnormally low; eventually finding a leak near the rear of the engine. No warning lights were illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the cylinder head bolts resulting in a coolant leak. The vehicle was not repaired. After investigating the failure, the contact related the failure to Technical Service Bulletin: S-SB-0004-11. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 287,000.

2009 Scion TC Woodbridge, VA

ENGINE

My scion TC is using an extreme amount of oil to where I am putting 2-3 quarts in the motor per week. The extreme usage of oil can cause the engine to blow up due to lack of oil staying in the engine. My oil light will flash after couple days indicating low oil. A dangerous situation that can happen is the engine stop working while I'm driving on an interstate and possibly cause a serious accident or even an engine fire. There was a Toyota bulletin on this issue back in 2015. My car was bought in 2013. According to Toyota, they claimed they had sent notice to the address listed under this VIN. We received no such notice and even requested Toyota prove they sent it, but they would not. When I asked them about this case in regard to this issue, they have mentioned Toyota would no longer deal with this because it was past the deadline. How can I be denied for a service bulletin if I never received the notice.

Warranty Enhancement Program – ZE7 OIL Leak Certain 2007-2010 Scion tC Extension of Warranty Coverage for 2AZ Engine Oil Consumption Toyota is now announcing the part replacement phase of Warranty Enhancement Program ZE7 for vehicles exhibiting excessive engine oil consumption. Eligibility for part replacement under this Warranty Enhancement Program is dependent on a Toyota dealer performed engine oil consumption test in accordance with T-SB-0158-14(Toyota) and S-SB-0031-14 (Scion). My daughter was never notified of this issue and they will not honor this and they told me it would have to be reopened in order for them to fix it at no cost to my daughter. Toyota needs to reopen this and fix my daughters car. The two letters that went out went to the original owner and I was told they used the DMV database which clearly had they it would have shown the date of purchase and the letter would have made it to my daughter. How many others did not get their car fixed are there more on the road with this issue?

2009 Scion tC consumes to much engine oil due to bad pistons installed by manufacture and needs to be repaired before major engine problems occur. I also found out I’m not the only one having this issue. I’ve just purchased the vehicle.8

2010 Scion TC Carpinteria, CA

ENGINE

I took my car to Toyota on August 7th 2021 and was informed my car needed a new engine due to losing three quarts of oil. The employee then informed me my car was under recall but they would be unable to fix the problem because the recall had expired. I never received a letter in the mail instructing me to take my car in for repairs due to this recall.

Warranty Enhancement Program –Part Replacement for Excessive Oil Consumption (NEVER INFORMED OF THIS ISSUE) I just found out that this expired on 3/27/2020 but Toyota mentioned this was created by your department. and within this letter we never received they are not willing to fix my car since it just started happening to my car. I took it to the Toyota dealership because I kept getting my oil changed at VA tire and Auto and after 2000 miles 4 quarts of oil is gone. They told me to take it to Toyota so I did and the service manger gave me a copy of the letter that was never sent to me in November 2015. I spoke to Carlos at the Toyota HQ in Texas and he said that they used the DMV website to find the second owner which is me and on my Vehicle Registration Card from DMV the Purchase date is 8/6/2015 and the car fax shows DMV reported me on 8/26/2015 new owner living in Winchester VA. Carlos explained to me that the letter was sent in May and November 2015 to Manassas VA which means it was sent twice to the 1st buyer of the car. I am thinking if this is happening to me there maybe others who were never informed of this situation. I was told by Carlos your department is the only one who can reopen this claim because I was never listed as the owner of the car that I bought 8/6/2015 and still own. I am hoping that you can help me get this claim reopen and because from the ways things look Toyota did not follow the rules of informing the correct owners of the vehicles on this Support Program they called it. Toyota said that your department did not feel it to be a recall. I would appreciate some assistance in this matter. I have all the documents proving I was the second owner. I contacted Susan Hogan for assistance because Toyota HQ said they are not responsible. My files are too big to upload I would need to email the PDF files to show you proof.

I PURCHASED A RED 2005 SCION TC FOR MY DAUGHTER IN FEBRUARY, 2019 FROM TOYOTA AUTO NATION IN DAVIE, FL. THEY HAD IT PRICED IN GOOD CONDITION, SO I EXPECTED TO GET SOME USE OUT OF IT. I PAID ALMOST $6,000. MONTH LATER IT OVERHEATED ON THE HIGHWAY (595) AND MY DAUGHTER HAD TO PULL OVER LATE AT NIGHT ON THE HIGHWAY AND I HAD TO HAVE IT TOWED TO MY HOME. VERY SCARY AND UNSAFE SITUATION FOR A TEEN. HAD IT TOWED BACK TO THEIR SERVICE STATION AND IT TURNED OUT TO BE A PROBLEM, THAT COST ME $600. I FIND IT HARD TO BELIEVE THAT THIS COMPANY WOULD NOT HAVE SEEN ANY DAMAGE UNDER THE HOOD. SHAME ON THEM FOR SELLING ME A CAR THAT BROKE DOWN IN ONE MONTH. I HAVE CALLED THEM AND THEY WILL NOT HELP WITH THE PAYMENT. IT IS 'AS IS' I CALLED AND TEXT THE SALES GIRL AND NEVER RECEIVED A CALL BACK OR RESPONSE. FINALLY PUT A BAD REVIEW ON THEIR WEBSITE AND RECEIVED AN E-MAIL TO CONTACT MANAGER TO HELP WITH THE SITUATION, ONLY TO FIND OUT THAT WAS AN AUTOMATED EMAIL AND AGAIN TOLD 'TOO BAD'. IT IS NOW JULY AND YET AGAIN IT BROKE DOWN ON MY DAUGHTER AS SHE WAS AT THE GAS STATION. IT WOULD NOT START UP AFTER SHE TURNED IT OFF. TRIED TO JUMP IT AND NOTHING. ONCE AGAIN HEADED TO GO TO THE DEALERSHIP SERVICE STATION. AT FIRST WAS TOLD IT WAS ONLY THE BATTERY, SO I SAY GO AHEAD, I WILL PAY THE $140 AND REPLACE IT AND WE WILL GO FROM THERE. ONLY TO GET ANOTHER CALLBACK FROM THE MANAGER STATING THAT THERE IS MORE WRONG WITH THE CAR, THAT AFTER THE $89 FIVE POINT CHECK ON THE VEHICLE AND REPLACING THE BATTERY THAT IT STILL DID NOT START. THEY WOULD HAVE TO KEEP IT OVER THE WEEKEND. IT IS COSTING ME AN ARM AND A LEG AND I NEED HELP WITH THIS. I FEEL LIKE THEY LIED ABOUT THIS VEHICLE AND ALLOWED A CAR THAT IS NOT SAFE TO BE BOUGHT AT THEIR BUSINESS. I AM CONCERNED FOR MY CHILD'S SAFETY AND ONLY WANT WHAT IS FAIR.

THE ENGINE IN THIS CAR WHICH IS THE 2AZ-FE HAS DEFECTIVE PISTON RINGS WHICH CAUSES THE ENGINE TO BURN AN INSANELY AMOUNT OF OIL. I LITERALLY HAVE TO ADD AT LEAST A QUART OF OIL A WEEK AND I BEEN DOING SO TWO YEARS ALREADY. I BELIEVE THAT'S NOT NORMAL AT ALL. CONTACTED TOYOTA TO NOTIFY THEM ABOUT THE ISSUE, AND CLAIMED THAT 'VEHICLE WAS OUT OF THE 10 YEAR OR 150,000 MILE WARRANTY'. I'M SO DISAPPOINTED AT TOYOTA FOR THAT. THEY ALSO HAD A PERIOD IN WHICH YOU COULD TAKE YOUR VEHICLE, BUT FAILED TO NOTIFY THEIR CUSTOMERS.

MY 2009 SCION TC HAS BEEN BURNING THROUGH OIL AT A FAST RATE CAUSING ME TO HAVE TO FILL IT UP WITH OIL EVERY WEEK. I STAY PRETTY LOCAL AND RARELY GO OUT OF TOWN WITH MY VEHICLE. IT IS CAUSING A VERY ROUGH IDLE IN MY CAR. I SAW THERE WAS A RECALL BUT IT HAS NOT GONE THROUGH WITH IT. BY THE LOOKS OF MANY COMPLAINTS WITH THE SAME PROBLEM AS MINE NEEDS TO BE FIXED. WITH NO OIL BEING IN A CAR IT CAN CAUSE THE ENGINE TO BLOW UP AND MY CAR IS CONSTANTLY GOING THROUGH OIL BEFORE EVERY 1000 MILES.
